if you had the psp and clicked the you would pull it up to your face and then mayby rtb would come up so you can get mods and they download as your playing and you can enable them while in one of your saves if you know wat i mean
I do not believe that is possible, to download them via RTB while in a server AND have them active in the server. I thought you had to
like update/restart the server to get new Add-Ons working.
On-Topic; Yes, I quite like the idea. Isn't there the 1x2 flat print brick print that had a BLP/BPP (Block Land Player/Blockland Portable Player. I can't remember which) That looks like a PSP but is, well, supposed to be Blocklands version.
