[Zope] and remote databases in other [zopes]

[codelarvs@ciudad.com.ar]

Hello! I have the folowing problem:
I'm using Zope on a SUN Sparc machine running Solaris.. 
The site works nice, but I need to access the data, that is
placed on a Microsoft SQL Server on a Windows NT and i cant change
that :\
I've read in the Docs when i was installing that is possible
to have a zope in each machine.. and use the one in the
NT like an iterface. For example: Lets say.. If I define a Dtml method 
that gets the data from the SQL in the zope in Windows NT..
Can I call that method from the Zope in the SUN to retrieve the 
data from
the Microsoft SQL?. If there's a way to do this (with
2 zopes or another way).. could someone please explain me
how to do it?

Thanks!
