Systems/Networking startups

Hi,

What is the trend you see for startups with emphasis on Systems/Networking, with respect to profiles of founders? What is the experience level of such founders? Any trends observed, with respect to funding and profitability of such startups? I was curious about this because the fact that there is significant lower entry barrier for web startups,was discussed in other threads.

EDIT: Please do also mention the names of such startups!
