A truly viable international language

by Hawg Wylde

I think that some of the most important considerations for a truly viable international language are as follows:
1. The greatest ease of learning for the greatest number of people.
2. The most easily enunciated for the majority of the earths population.
3. An alphabet that is easily mechanically reproducible using currently available hardware, I.E. keyboards, Typewriters etc.
4. A vocabulary that utilizes the most commonly used word roots, and incorporates words, acronyms and expressions that are currently internationally used/recognized.
5. The possibility of widespread acceptance and eventual adoption.

In the past I had very high hopes for Esperanto, however I now believe it has one fatal flaw that will condemn it to oblivion. That flaw is its Accented letters. The work around of using X after the accented letter is disconcerting to say the least and to my mind is not a viable fix.
I'm currently looking into Mondlango/Ulango and am at this point impressed with what I see, if it shows any potential of really taking off I intend to adopt it wholeheartedly.
