*sigh* anyways.. venting over..
You have an awesome tool - couple of queries.
condensed:
Anyway to stagger whois queries to get around limits?
What sort of bandwidth/cpu time are you worried about using - you on virtual or dedicated?
Perhaps appending an "s" could just be an option like the hyphenated option instead of a large combined list.
this is how I'm currently using your script:
two Overture STS Tool pages open to check overture # results and children variations of main query list in far right. Your page + notepad to save results. registrar and wordtracker minimised but used often.
An extended query service to combine these functions would be great. An elongated service perhaps taking 30 minutes that checked all TLD availability, merged, hyphenated, pluralised and all related search terms from parent query and expanded children results with overture #'s returned either as an email or protected area for a paypal or similar fee. Juxtaposition with wordtracker or similar's results would be ideal though likely impossible.
advertising.
trial enom reselling @ $9.95 per domain. (can't guarantee better than ads by google though) depends on traffic savvy.
link to SEO affilaite programs such as (now defunct?) seguru.net
contextually return sponsors based on search query - a search of "anal" returns links besides domain results to 5 anal sponsors you are a second tier affiliate of to combine your script into a domain search and domain revenue tool.
mark domains expiring soon with a tombstone or similar that links to pool.com or similar's affilaite program to catch drops.
