isn't this exactly what is achieved by providing radb? including the 
individual's routing policies, so my system can find a nice compromize 
between what the providers around me want, and what I need?

'in spite of': guess the job is done just for that.

For me, it is important to have access to routing info and policy 
advertisements, so I know better what's going on around us here.

... and if someone wants to make it a secret: hint:

from ... accept any
to   ... announce <mine>

with this, your routes are all represented, your AS is well defined, and 
what your route maps do (in cisco lingo), or your netsentry, or your 
filter, is your private issue. No reason not to participate, even with a 
blank statement like the one above. BTW: mine is blank, because I do a 
conservative approach: accept anything, announce clean. ;-)

Or tell anybody how you want it, guess what: bgp makes it happen as close 
as possible.(with RS and some little wood shims, no effort no gain of course)

Database format: a fight about 'better' or 'worse' is , mho, just stupid: 
better changes with time. New features bring new ideas and new needs for, 
guess what: new features.

The evolutionary process is the best one, since 
every worthy contribution will prevail, and good meant tries will vanish 

The informal process existing is excellent too: no red tape for real good 

To me, the radb is worth a hell of a lot for all kinds of tasks, not only 
routing (e.g. location, performance tests, yni).

I personally say here: this is a good thing, no matter from where it 
comes. And if a provider with particularly bright and friendly people is 
heavily envolved: the better for all the others, no?
