Comment (by cypherpunks):

 I'll revoke comments [ticket:15515#comment:14 14],
 [ticket:15515#comment:17 17], [ticket:15515#comment:21 21],
 [ticket:15515#comment:22 22], which is about ability to process introduce1
 cells as long as not any ACK'ed yet. It's not fun to allow IP so easy to
 know one client want to visit HS1, HS2, .. HSn, HSn+1, even if it nothing
 knows about HS1..HSn. One intro circuit allows only one introduce1 cell is
 valid and legit limitation for intro circuits. Has no more questions to
 this ticket then.
