yeah fast packets should let us do this
someone make an addon so badspot doesn't shut down blockland from coding frustration
such an add-on would both have to patch things that are not accessible to TorqueScript as well as making clients do the same, neither of which are or should be possible
raising the color set limit is perfectly possible with a DLL but requires all clients to also use it lest they not be able to play at all
datablocks are not an issue seeing as you could simply use the same 7 datablocks for the entire colorset, regardless of how many million colors there might be - having the spray take on the color is a nice effect but is really not needed when the alternative is using many more colors while using barely any datablocks
of course, you can change the colorset on a server as you switch between different builds or even modify the colors of a colorset while building just fine, partially solving the problem, but no matter what you try you can't add more colors just from an add-on that will just work for everyone
you can have unlimited colors in single player however by changing the colorset as you recolor bricks, since that won't affect existing bricks
