I have upgraded to the latest release of JoomSEF 2.1.1 and have it working with HP 1.0.0 extension.
And have been able to replace HotProperty appearing in the URL (replaced with something else) using the Configuration table (component page titles at the bottom).
One other thing... I was then getting the default property page always apearing.
This thread provided a fix for that...

...and with a few custom renames.. i'm all sorted and happy now :-)
