Distributed Database Web Site

Just curious, how hard would it be to distinguish on the main web site
between read and write operations?

For instance, if we had a read-only database on a mirror site, replicated
from the main database using something like Slony ... how hard would it be
t have 'write operations' sent to the main web site to happen, with all
read operations being local?

ie. posting news events would happen at http://www.postgresql.org, but
reading news events would be @ http://www.xx.postgresql.org, but both
could/would be dynamic?
