The problem (in my case) is that I am forced to NOT use the same or even similarly connected upstream routes, for some of my locations. Some go through Teleglobe, Taide, C&W, Level3.

This is the point - I am, sort of. Were you to implement your filters, I would lose connectivity to you so I would be forced to:

In fact I do have a /24 from one of them. However they are so incompetent, that after 18 months I still don't have RDNS authority for the /24 assigned to me (not for lack of trying, trust me). Would YOU use any netblock, you didn't have RDNS control over? No RDNS, and stuff starts breaking - starting with mail delivery which in itself, is sufficient reason to avoid using it.

Ah, now you have the unanswerable question. If you do find an answer, perhaps you'd consider attacking spam as your next project :) Frankly, I think you're beating your head against the wall and you have said as much yourself in acknowledging that you face an impossible task. For sure, though, continued efforts to educate those who announce /24's and smaller is a step forward, if a small one. I can't honestly see the 'problem' getting any better - for every one you educate another one will pop up who needs a spoonful of clue - such is the nature of this industry, unfortunately.

I think our time would be better spent beating people like Cisco around the head, for their insane pricing. I have 1.5Gb of perfectly good memory in this workstation, for goodness sakes, that cost me a fraction of what 256Mb costs in a router... I feel your pain ($50k is no joke) but I think you're venting the result of the pain, on the wrong people... the routing table's not going to get a whole lot smaller in the foreseeable future, despite our best efforts...
