Exactly. _Productivity_ is a factor I was going to add, but it wasn't part of
the problem at hand. Having various different shared servers, let alone
different hosts, leads to multiple addresses, passwords, fragmentation of
support, lack of familiarity with the staff (which can come handy) and the
list carries on and on...

Hope it helps,
