It would be fun, but on the other hand, to my understanding a library employee's idea of "good money" looks an awful lot like a technologist's idea of "OMG I am going to lose my house."
I also recommend checking out LibTechWomen[2] and Information Technology and Libraries[3].

Being a technologist for libraries sounds awful, though. They deal all day w/locked-down journals, proprietary databases, the MARC formats, and various systems from the 60s - and I'd need more than I make now to work with that crap.
For shame.
