Yeah, that's it!
This script contains two particles: RCRT and RDLT. Their uses are below:

RCRT is the remote creator. On spark it creates a particle:

• of type equal to its ctype
• at position x equal to its tmp
• and at position y equal to its tmp2

RDLT is the remote deleter. It is almost the same besides that it, of course, is not using ctype. Because it is deleting particles, obviously.

Hope that is a good thing, maybe it will go into official?

Woah, forget 'bout the link! Nevermind, it is here: http://pastebin.com/hCBuxa06
