Demonstrating progression in career [all opinions r welcome]

Topic theme:
Demonstrating growth during employment is one of the prime factors of a successful MBA applicant. However seldom are there chances of a rapid and flexible career growth, especially when you are working with a company that among Fortune 5. In such cases how do you demonstrate "professional growth" in your application?

Brief explanation of why I am asking this:
My profile in brief: The company I work for is among Fortune 5, and since graduation from a very prestigious college (the best bachelor's in Mechanical engineering in India), I have been working for my company in various functions and in various places (Singapore, Netherlands, middle east, Western Europe, Australia) and at various levels of the organisation. I have been working for 1.5 years till now, and am thinking of applying either in 2009 or 2010 depending on how mature my profile is for getting in. So when I get in, I am in either with 3 or 4 years of experience. While there is still time to go, I have now time to improve what I work on depending on what I can achieve. I am only looking for the top 10 MBA programs (and nothing lower)
While my other dimensions in extra-curriculars, community, skills etc. have been fairly strong... one thing that worries me is "growth during employment".

The worry is because my company despite offering a "rosy" work experience is a global company, and very big (euphemism for bureaucratic). It's graduate development program is supposed to offer us several different postings, while offering us a flavor of the business. Therefore, at the end of 3/4 years it is very likely that I might end up not having any people reporting to me, or with a significant growth in managerial responsibility. Also mine is a consulting kind of role, which at my age almost literally means getting more experience and knowledge before I can really assume significant responsibilities.

Under such circumstances:

1. Is there anything I can/ should do within my organisation to improve the way I can demonstrate my professional growth?
2. If I could do nothing in 2 more years, is the application still strong if I have a good track record of performance?

While a reply from the professional is definitely expected... I am also looking for other members who can share experiences :
