Maximum PC

Can you install Microsoft SQL Server 2008 (the full product, NOT the SQL Server Compact edition that comes with VS.Net), and MySQL on the same machine without conflicts?

I know that each uses different port numbers to communicate with apps, but want to make absolutely sure before I do this on a production PC.
The reason being that we have a purchase software package that uses MS SQL Server, and I've created a few in-house custom-written apps myself that use MySQL, but they both need to be on the same machine and running at the same time. My biggest concerns are communications issues (queries going to the wrong server, or one server not starting because it detects another SQL server program running on the machine).

Ideas, suggestions, or opinions?

Nope, no problems at all.

I figured so, with the port numbers being different. With two web servers I could understand if there is an issue since they all listen on the same ports, but since different SQL systems use different ports, this should work.
