I wish Chad all the best - he's a brilliant guy. For my situation VBA makes more sense. However, it (VBA) pales in comparison to ODCL. SharpLISP and ODCL could've been a great tool for every AutoCAD user and an economic bonus to companies wanting to streamline their drawing process. But alas DOT NET, Revit, and the like have put an end to development in LISP. Sad.
Good luck Chad.
