Is anyone using SQL Server under VMWare and doing development on a mac?

I'm at work, and I have to use SQL Server. For local development, I
have SQL Server running in Windows XP in VMWare. I'm trying to use
TextMate and Mac OS X for rails development and connect to SQL
Server.

Has anyone tried to do this, and has it worked?

I'm running into several problems
1) I have VMWare's network settings on Correct Directly to the
Physical Network. I can ping from XP to Leopard, but not vice versa.
Is this a good idea?
2) I cant get OSX to communicate with SQL Server. I'm trying to follow
these documents.

If anyone can give me some help, it would be much appreciated! Thanks.
