John,

  The easiest way is to look at /proc/net/sdp/devices, the second line
contains the number of connections in the SDP connection table. There
will be a connection for every SDP socket that's open, including listen
sockets. There are also a few files in the same /proc directory which
have a line of statistics per connection in the table.
