We try to stay away from specific recommendations, because almost 100% of the cloaking software authors on the web are regular readers and responders in this - one of the only - cloaking forums on the web.
How to choose:
a) be specific about what capabilties you need.
b) get specific about your requirements. - webserver, platform, package, language.
c) note what type of support you feel your are going to need: regular updates of ip addresses. Alternative language/agent/ip/country/format/rss/xml/hmtl page delivery you are going to need.
Once you get specific about that list of items - your choices are narrowed down to a few. Then you are going to need to have a run through yourself and decide.
Please do not mention the names of specific cloaking software applications. If we allowed that, this forum would quickly be overrun by people advertising their programs. See the Forum charter [webmasterworld.com] for posting guidelines.
