>These type of arrangements happen all the time. Contrary to other replies, they do work, and can work well, provided you have a clear definition of who does what.

And just this creates problems for me.
As example: we made for a London based partner a few applications and discuss this possibility.
He got a project from other company. Everything is OK. We have made prothotype. Investor say OK we make an evaluation. they agree with it, but said that they like to make application in style provided by their programmer.
And this staly was a mess between old FP code and VB code
and we stopped the project.
Would you like to provide any other examples???
