Thank you.
Getting the current PageRank can be difficult. Google try to make this hard.
Google may think you are abusing its trademark and ask you to stop displaying it, or just sue you.

LOL. If you know all about PageRank why do you have to ask this question? Using a tool that was created by reverse engineering the Google Toolbar DLL you might violate Google's TOS. Google doesn't want your proper credit and it doesn't want to be abused. It's up to you wether they catch you or not.
Anyway, here's a hint:
WWW::Google::PageRank is a Perl module that gives you the toolbar PR value for any given URL.
Legally and (arguably) ethically I would steer clear of it. Brett recently commented (msg 2) [webmasterworld.com] on the definative ability of google to distinguished the cracked algo from real requests. I wouldnt want any of my work to be hosted on an IP associated (repeatedly and regularly) with violating googles proprietary formats.
What would be the purpose of displaying PageRank next to the listings?
There would not likely be any legal action beyod a C&D, but if you in any way depend on google for any of your traffic, they can cut you off.
I think I might write an email to Google, and see if I am able to get an ok from them.
Thanks to all of you for the very helpful replies.
Problem 2: Google trademarks infringement, etc.
Solution: Use another name and change the color of the bar, etc.
Google would have a hard time in court and wouldn't bother suing. On the other hand, they could remove your site from the index if you were foolish enough to not cover your tracks.
On the subject of Google being able to identify legit requests from hacked requests, there may be some truth in this, but not as much as Google would like us to believe. Depending on what entry points are available in the GoogleToolbar DLL, on a Windows system, it might be possible to use the DLL itself to send the requests - these would almost certainly be indistinguishable from legit requests.
Kaled.
If they catch it they ban your other server, big deal, keep getting new ones with different IPs.
Doesn't seem like to much of a risk and with this method your main site won't get screwed if you follow the other advice and cover your tracks well enough and don't outright say, "checkout google's PR for this site" type of stuff.
The Toolbar DLL uses the HTTP protocol to communicate with toolbarqueries.google.com. Some big firms use proxy servers to provide internet access to their employees. The Toolbar has to communicate through the proxy as well. Sometimes they have thousands of users hidden behind a single proxy IP address. How on earth is G to find out whether it's a PR-bot or just a big proxy?
Run your script four times a year - the PR updates won't be more often anyway.
Query one url every 5 seconds on average, randomizing the delay between 0.5 + X seconds and 9.5 + X seconds.
Pause the script between 7 pm and 9 am.
Make X a function of the time of day, X being 0 at noon and 10 in the morning and evening.
Maybe G does it the same way and that's why it takes them ages to update the darn toolbar PR. On the other hand, in dubio pro reo doesn't seem to be G's motto. G bans sites if it feels like they violate the TOS. It doesn't matter whether there is actual evidence.
Google doesn't want your proper credit and it doesn't want to be abused.
And you are who?
The best way to find out if you can use it without the risk of getting banned is to email or telephone Google (sticky me if you need the number). But, I'm willing to bet they say no. So if you're waiting for approval you're not going to get it any time soon so just go ahead and use the sneaky stuff being suggested in this thread.
