Hi Vincent. Not sure if you are affiliated with SQL+, but just in case you are, you / the group might want to consider that "SQL Plus" is a registered trademark of Oracle Corporation, as seen via the following link (please click the "LOGOUT" button when you are done viewing that page):
I am mentioning this because whoever is selling "SQL+" is going to want to contact a lawyer who specializes in patents and trade marks ASAP to inquire about this name similarity. I am not a lawyer, but based on my personal experience, I am pretty sure that the "*" in the official name of Oracle's tool, "SQL*Plus", nor even the ".NET" in "SQL Plus Dot Net" (that it is only occasionally referred to as), are enough of a difference for the two product names to be considered different. Keep in mind that the US Patent and Trademark Office does not have subcategories for "Software": all software is lumped together.
