Probably, but with a good pricing model and an easy to use system (maybe a ssl-wrapped caching proxy or an ssl vpn) to send the logs over the wire for processing and storage would attract the attention of the devops world (which is worth about $3.50) Then you could just tell everybody, "it's like splunk, but in the cloud, and affordable". Fame, fortune, and the critical logs of hundreds of new startups would quickly be yours.
