Pooling with SQL2K

I understand that connection pooling is currently only available for protocol 
version 4.2

I would like to use pooling with SQL2K and so understand that code will need to 
be changed to accomplish this.

I have begun reviewing the pool source and would like any input that could be 
provided reagrding the types of changes that should be made to support other 
protocol versions.

Are the changes "addtional" in nature, meaning that more code needs to be added 
to handle multiple versions or are they "rip and replace" type changes that 
lead to the code currently being used for 4.2 being replaced as well?

Can you point me to anything that might not be obvious in other portions of the 
"main" tds code base as a guide?

Are there any "land mines" that I should be aware of in attempting to implement 
these changes?

I cannot commit that I can effect these changes but I am serious about making 
an effort to assist this great project.

Thanks!
