I've seen dual socket A athlon XPs and dual socket 370s. But never a dual socket 478, why is this? Too expensive? Probly wouldn't cost alot to run dual celeron 2 ghz...

Its because Celeron is the low end of the Intel CPU line. If you are going to spend the extra money for a dual CPU system you may as well buy a high end configuration.

There is no such thing as dual socket 478, for pentium 4 ... The closest thing is the Pentium 4 Xeon, but it uses another socket ...

This article pretty much sums things up:
