Tony,
If you want my "soon to become a paying client" opinion: forget those LTH developments and get me MY CBE asap...
Since you already have a good customer base that will stick around for the next 3-5 years, then forget the ones that haven't had a chance to pay you yet (and YES, believe me, they all want to pay FI asap!).
ps. Don't delay restarting the work on the LTH when my CBE is shipped.
