Enigmae has already looked for prior work; he said that at the beginning of his post. It seems to me that he's only looking to start from scratch if what he's looking for isn't available. In the event that he must roll his own, his goal doesn't seem to be simply learning:

What I had in mind was to use perl to create a powerful application framework that can provide a mechanism to easily multi-task and solve problems using several machines and be easy to intergrate in existing and future projects.

He has a very specific need to fill. Systems (like Mosix) do exist which could solve the problem, but it doesn't simply follow that others shouldn't be created. Since he says he needs to combine with "existing projects," the existing solutions may not work for him. His existing logic may not map well to fork(). He may need to use it in conjunction with Solaris, WinNT or Plan9.

Anyway, if somebody wants to make a pure perl solution for something, more power to 'em. I could use it for what I'm doing right now, currently non-parallel, across the Linux/Solaris divide.
