It has been too long since I have been here, but I am back again

I have script request and I have no idea how hard or easy it may be. But here is the main idea....
I am using Netplay 1.7.3 with the new server made by nowayskills or something over at
RMXP.org, basically it is 1.6.3 with a few extra features and fixes, but the new server I am using also includes no lag
But it saves to the computer of whoever is playing it, so what my request is, is something that would save and load from...
www.something or
ftp://something/saves/*username*/
this is very basic but maybe an ftp where is creates the folder by the name of the user and then saves and loads from that network address, of course I will make it so it has annoynomus access and stuff, kinda unsafe but yet no one shall know the address unless they really try.
Can anyone please create a script that shall do this?
Thanks
