We've had several discussions here regarding the use of meta refresh when 301s were not possible because there was no access to the .htaccess file. I don't know for sure what John Mu's answer would be in these cases... and there's no doubt that proper 301s would be better... but I suspect he'd view the problem from a slightly different angle.
See these earlier threads...

Using Meta Refresh for redirect - when 301 is not possible
There still has been, as far as I know, no official confirmation from Google about how they do treat meta refresh in such situations.
