ODP.NET

Here is what I need to do: I need to keep the 'production' version of ODP.NET (10.2.0.1.0) installed for my Visual Studio 2003, yet also install the beta ODP.NET for Visual Studio 2005. In other words, I have the Oracle 10g client 10.2.0.1.0 installed, and want VS 2003 to use ODP 10.2.0.1.0, and VS 2005 (on the same machine) to use the new ODP.NET beta.

Questions:

1. Is this possible? I believe it is, cause I think I have tried this before, but I remember I ran into some issues. Which leads to the next question...
2. What exactly is the 'install' sequence to do this? I.E. I already have ODP 10.2.0.1.0 on the machine, and now what to install JUST the ODP.NET beta (for VS 2005). If I remember correctly, what happened before was that it either (a) Installed the new beta of the ODP for VS 2003 (which is not what I want to happen) or (b) I didn't specify ODP for 2003 in the beta install and it removed it entirely.
3. And finally, is there any way to JUST install the ODP 2005 beta without anything else? And can that be automated?

Basically, I want to install the ODP Beta (possibly with the VS 2005 developer tools also) but NOT touch nor remove the ODP 10.2.0.1.0 production version so that VS 2003 keeps using it.

Any advice/instructions appreciated. Thanks in advance.
