I'm not a big fan of the Signalink, because it is essentially a VOX/SOX device,
which means in some situations, it can be unreliable, and in all situations,
there is an increased delay in keying the PTT.  I prefer devices with a
positive software or hardware generated keying action.

The soundcard/software modems themselves work very well, these days, often
better than many hardware based modems.

You can also use a software modem called WINMOR for HF Winlink.  I have used
this to send email from remote sites in the Austrlaian outback.

 ZR> Yep we have those also!

There's not as lot of packet infrastructure here, other than for APRS. interest
has waned.  I am looking at setting up AX.25, NET/ROM and IP over packet here. 
I'm also wondering if I can ovver IPv6 over packet.  I do have plenty of spare
addresses (I have a /56 here, only using a /64).
