I was hoping somebody could clear some confusion I have over Excel 2003 and
remoting.

At my work, a 3 tier web application is being built, and they are using
remoting on the application server (not web services because the lead
developer says they are too slow and "not secure"). The application server
will be developed in C# 2005.

I need to call some of the server based objects through Excel 2003,
preferrably using VBA.

I understand that it is possible to get Excel 2003 to talk to web services,
but what about when the server is using remoting ?

Is it true that:
- Excel VBA can only talk to a server that exposes web services
- VSTO is not as limited as VBA ... it can talk to a server that exposes web
services OR remotable classes ?

Sorry if this is a dumb question ... I have tried googling this issue but am
going around in circles!

TIA
