Currently I have 2 choices as far as I can make out, give them a bit of my /19, break up my nice aggregate and ensure loads of extra announcements (and that probably none of them get routed by anyone applying prefix based filtering), or give them a new /19 all of their own (you've said it, that's the minimum size allocation) which actually solves their problem and mine, but this isn't an option currently available because currently it's one window per local-IR. So they have to go and become a local IR.
If the high /21 of your /19 is not Allocated, you just assign it to them and add ONE announcement of the /21 to supersede with the current /19. If it is not free but is sparsely populated you can move the stuff out to free it up or go to RIPE to get your /19 turned into an /18 (ie: get the /19 right after your current /19 [RIPE did give you the first /19 in a shorter prefix block didn't they?]) in exchange for returning the /21 worth of space [giving you 3 extra /21s worth of space], and divide that 2nd /19 into a /20, and 2 /21s giving them the 2nd /21 (still doing the same 2 announcements as you would if allocated out of your current /19).
