Any thoughts on the meta refresh would be appreciated!
Some accessibility and usability problems for older browsers [w3.org...]
You cannot tell how SEs treat it really and what they'll do in the future. There are hints these pages are treated as 302 by some SEs and 301 by others and I don't know how they perceive content of the page with the meta-refresh.
It also depends on the implementation. Some cases could justify its use but I don't think is a good replacement for server side redirect headers.
