Is it permissible to advertise number resources allocated by one RIR to a ISP in a region governed by a different RIR? Practical?

I believe all the big multihomed multinational organizations generally
all do this; the ones I've worked with (banks) all did.
It would sort of defeat the purpose of multihoming if you couldn't
announce not just to other providers, but in some circumstances
multi-geographically. If my multihoming crosses a RIR boundary it's
still multihoming. One of those RIRs is probably "home territory" to
ask for allocations from, but in any case there shouldn't be a
technical or policy block to anouncing ARIN space in RIPE land, or any
similar variation thereof.
