Perhaps some of these questions are relevant:

1. what developer skills does the shop have
2. is this a small one-off
3. are standards involved (or should they be)
4. who maintains the home-grown software and for how long
5. casting doubt on middleware without being specific about which
solving what purpose is self-defeating before one even starts
6. employing standards-based software (no, I do not mean TCP/IP
sockets, but do realize that they also adhere to a standard) generally
leads to further opportunities
