Hi Tor-Talk,

I am interested in the scaling limits to Tor and what present the bottlenec=
ks to Tor=92s future expansion.  I have looked into the documentation avail=
able and see that Tor has far exceeded initial projections through structur=
al changes to the relationships between clients, DA=92s and relays.

Two of the bottle necks identified in dir-spec (section 0.3 Some Remaining =
Questions) are that having every client know about every relay; and to have=
 every Directory Cache to know about every router won=92t scale ad infinitu=
m.

Is there a known threshold that on the horizon that you are aware of but do=
n=92t need to address at this stage?
What are the limiting factors to the unchallenged scaling up of Tor to the =
multiple million users and nodes?

I would like some guidance in where these pinch points are so as to researc=
h this in greater detail.

Yours sincerely
