[stunnel-users] Stunnel Scalability Question

I have an application with the following characteristics and am trying to
determine if Stunnel would be a suitable option for securing my
transmissions (in particular, will it scale):
- Each of my clients is connected to the Internet via a 56Kbps modem. My
server has whatever bandwidth it needs.
- Each client "transaction" consists of (a) connecting to a central server
using a TCP/IP-based protocol, (b) uploading a 512KB block of data and (c)
- Our server needs to be able to handle 2000 concurrent clients under peak
- Under the peak load above, I would like to limit the time a client takes
to perform a "transaction" to around five minutes or so (uploading 512KB
at (56Kbps / 2) = 28Kbps should take ~2.5 minutes).
My questions are:
(1) Do I have any reason to believe that Stunnel will simply not be able
to scale to handle the load described above (i.e. a steady load of 2000
concurrent clients connecting, uploading half a megabyte of data and
(2) If Stunnel can handle this - do you have any thoughts on what sort of
machine (or machines) I should be running my server-side Stunnel daemon(s)
on? I am particularly concerned about CPU usage.
I apologize in advance for any overlap between this query and past threads
in the archive/information on the website - I wanted to make sure that I
ran the specific requirements above past somebody with experience using
