Sorry... I don't have all answers to all questions.

I just can say that I tested SQL*Forms 3 over SQL*Net V1 (Unix to Unix) using a 9600 slip conection. Performance? Bad!!! Unusable.

I recomend you to make lots of tests before anything, despite you're going to read here.

I read that SQL*Net v2 is doing better, but I didn't test it.

Be aware to LOV; SQL*Forms usually retrieves *all* rows of the select and then filters them using the criteria you typed. It can kill the performance of your application! Try to put *aways* a "where clausule" on your LOV's select to filter the rows according to a previous typed mask (using list_values( restrict ))
