As I have said in this forum before the address allocation policies RIPE
uses are in line with IANA's policies, RFC1466 and the current draft of
RFC1466's successor.  The policies are published and regularly discussed
with ISPs in the appropriate fora such as RIPE meetings, NANOG, IETF etc. 

The current policy is that the size of the *first* allocation to any new
local registry (ISP) is /19.  Of course we will *place* such allocation
such that the possibility for future aggregation is maximised. 

These policies are not subject to change based on routing policies set
by a single ISP or a small number of ISPs.  Otherwise a single ISP would
in fact be setting the policies.  Of course rough consenus among ISPs is
an entirely different matter; however this is not apparent on the
prefix length filtering issue.

We charge *everyone* for registration services.  That is how it should
be.  There is no reason why governments (read: taxpayers) should be
footing the bill.

*used to be* smaller.  At NANOG Sprint announced that their filters will
be /19.  This should be implemented "in the next couple of weeks".  Also
most of the RIPE NCC's allocations are out of 193/8 and 194/8 which were
never filtered by Sprint.

We are working quite closely together indeed. 
But sometimes there is no rough consensus.
