I dn't have a lot of experience at this but I can say that at least one person whose experience I trust recentlyreported in Rhelp that RSelenium tends to be a fragile interface. Nonetheless, he does use it on occasion and it clearly "works" on more than one platform. If your code is not confidential and the website has at least a guest login capacity, you could post it here and ask for trial runs on whatever platform(s) you may not have testing capacities for.
