I've written a wordpress plugin [1] to simplify Analytics installation
for bloggers who don't code, but there is still a cut'n'paste element
necessary with the current "here is some javascript" system.

I'd like ot be able to make the whole thing user-proof, so if I could
retrieve a list of _uacct numbers for the available channels that would
be a great boon (or if the API enabled my plugin to send it's domain
and just return a single match, that woud ddo).

Does such a thing exist?  The help pages aren't responding at the
moment, so perhaps someone knows.

Cheers
Rich
