Chris,
There are a few issues I had when I took the main server to V5, nothing that
couldn't get sorted in a day or two though, but it did require a quite a bit
of revalidation for existing code.
If you need LAMP hosting space with V5 then give me an email off list, I
already do this for a few people selling / designing sites.
