I just did a search of Ryze's networks and came up with a network called Entrepreneurial Exchange Network. You might give that a try. Plus, you can always do a Google search and see what pops up.
To my knowledge, the most successful leads exchange group is BNI (Business Networking International). However, unless the rules have changed, BNI requires physical attendance at its meetings and you are not in a position to do that.
Have you tried looking at Google Groups or Yahoogroups regarding lead exchange groups?
