I'm curious if anyone has ever had any experience with Objective Systems Integrators (OSI) product NetXpert. They were recently purchased my Agilent and their product was primarily sold to CLEC's, large ISP's and telco's (both in the US and abroad). They've taken what looks like the Netx product, cut it's price and are now trying to sell it as a managed service application. I've done my research on deja and other resources but haven't turned up anything so far. Any info anyone has would be great. OSI has been great about providing info as well, but I wanted real world expertise. Michael
