yes, the hub embedded in Aladin is the JSAMP one, so that will work.

ds9's send-to dialogue will presumably only list clients which 
have declared themselves able to receive images (or whatever is
being sent) - in the jargon, clients which are subscribed to the
relevant MType (such as "image.load.fits").  So, if you have not
configured your python client to be so subscribed, it won't be
shown as a send-to option by ds9.  I'm not the SAMPy expert, but
I think you use the SAMPClient.bindReceiveCall() and/or
SAMPClient.bindReceiveNotification() method to do this.

As far as I know, the only SAMPy example code is at

   http://cosmos.iasf-milano.inaf.it/pandora/docs/samp/

and maybe in the SAMPy sources.  The general purpose MTypes which 
define message semantics are documented in the link from

   http://www.ivoa.net/samp/

If you're developing code, you may find some of the diagnostic
tools in JSAMP (http://software.astrogrid.org/doc/jsamp/) useful.
